RIM is planning to release a suite of new smartphones and tablets in 2013 that run on the new BlackBerry 10 operating system, according to a document that appears to be the company's product roadmap for the year, which was obtained by BlackBerryOS through an anonymous source.

The document shows that the company plans to put out two new BlackBerry smartphones in the first quarter of 2013 that run on the new operating system, which has yet to be released. One of these devices, which is codenamed London, will be a touch screen, while the other, codenamed Nevada will feature a physical keyboard.

RIM's plans also indicate that the company will release a 4G-version of the BlackBerry Playbook at the end of this year, followed by a new tablet codenamed Blackforest in the third quarter of next year.

Aside from these three devices, the document also points to two other mystery products to be released in 2013, one codenamed Nashville and the other codenamed Naples. BlackBerryOS speculates that these devices could either be versions of the N-series smartphone or else different-sized versions of the Playbook tablet.

RIM had previously planned to release the BB10 operating system this year, but recently announced that it would be pushed back until early 2013. Some have speculated that the company might never be in a position to make good on releasing the new operating system, but if this document is to believed, RIM is planning for a busy year.
